Acute myocardial infarction (or heart attack) is one of the serious acute cardiac events, and this disease, which can cause instant death, is getting closer and closer to us. Since 2005, the mortality rate of acute myocardial infarction has been increasing rapidly, and it is estimated that there are 2.5 million patients suffering from myocardial infarction in China, but only 5% of them have received timely and reasonable treatment. Acute infarction is a very serious type of coronary heart disease, the main cause of which is coronary artery occlusion and interruption of blood flow due to coronary atherosclerosis, narrowing or blocking the lumen, drastically reducing or interrupting blood supply, and necrosis of myocardium due to ischemia and hypoxia, resulting in serious irreversible damage to heart function and high mortality. However, the time dependence of heart attack treatment is very high, and heart attack treatment seizes the golden 120 minutes and opens the infarcted blood vessel as early as possible can reduce the mortality rate of patients and improve their postoperative quality of life. Therefore, the State Council approved the establishment of “National Heart Attack Treatment Day” on November 20 every year to further improve the level of heart attack treatment nationwide, popularize related knowledge to the whole society, and advocate the scientific concept of heart health. Which groups are the “meat and potatoes” of heart attack? The first and most important thing to note is that patients who have clearly suffered from coronary heart disease need special attention, however, those who have suffered from hypertension, diabetes, high blood pressure, smokers and alcoholics, those who are in a long-term high-stress state, those who are mentally stressed, obese patients, those who stay up late for a long time, those who do not exercise or rarely exercise unreasonably, etc. are all potential groups of people for heart attack to occur. The more of these risk factors you have, the greater the chance of myocardial infarction! Avoid the risk points in life that induce the occurrence of heart attack! The onset of myocardial infarction disease is usually very urgent, so that patients and their families are caught off guard and cannot be treated in a timely manner, and in serious cases, the lives of patients are endangered. Professor Fang also introduced several situations that are prone to heart attack, the gentleman does not stand under a dangerous wall, people in addition to the prevention of the above-mentioned risk factors for heart attack, the elderly and patients with coronary heart disease should pay more attention to the following situations: 1, be alert to the peak of the onset of winter and morning. Many years of clinical observation found that the onset of acute myocardial infarction has two significant characteristics: first, the most incidence in winter; second, the most incidence in the morning of the day, which we call the “devil’s time” of cardiovascular disease. (1) Sudden cold stimulation may induce acute myocardial infarction. Because when the temperature drops, sympathetic excitation, small blood vessel contraction, blood pressure increases, heart rate accelerates, metabolism is enhanced, while the blood fibrin increases, platelet activity is enhanced, all this makes the blood viscosity increases, prompting the formation of thrombus. Patients with coronary artery disease should pay great attention to prevent cold and keep warm. (2) Early in the morning, due to the biological clock effect, the sun rises, the body wakes up, sympathetic excitability increases, the concentration of various hormones in the blood rises, and the physiological metabolic activities are enhanced, which makes the blood supply to the existing lesions of the heart and brain vessels insufficient, and the situation is further aggravated, prompting atherosclerotic plaque damage or rupture, and heart attack occurs. People with heart attack risk factors should pay special attention to this time, it is recommended to wake up a glass of water. 2, stay up late: often stay up late to disrupt their own biological clock, will make the sympathetic and parasympathetic nerves in a dysfunctional state; meals, rest irregularities will cause low sugar and low potassium, electrolyte disorders, resulting in arrhythmia, which is an important cause of sudden cardiac death. In addition, staying up late for a long time can form blood clots and block blood vessels. 3, excessive fatigue and continuous tension, excitement, etc., can significantly increase the burden on the heart, the sudden increase in myocardial oxygen demand, resulting in a short period of myocardial ischemia, hypoxia, myocardial necrosis – myocardial infarction. Heart attack has the role of congenital genetic factors, but also the influence of acquired bad lifestyle. In the current situation where people are not yet able to change the congenital factors, it is more important to change the poor lifestyle. Sudden heart attack – “time is life” Acute myocardial infarction is often preceded by aura symptoms. Within 1-2 days before the onset of myocardial infarction, patients will have more angina attacks than before, and the effect of taking nitroglycerin tablets is not obvious. Patients may feel severe and persistent pain under the sternum or in the precordial area, or dullness and discomfort in the precordial area, and the pain sometimes radiates to the arm or neck, accompanied by symptoms such as pallor, panic, shortness of breath and cold sweat. Some patients have no severe sensation or show sudden severe epigastric pain due to ischemia in the lower wall of the heart muscle, but it will manifest more severely, and rest and taking fast-acting vasodilator drugs cannot relieve the pain. If the above symptoms occur, it is highly suspected that the patient is having an acute heart attack, then he or she should immediately lie down and rest, notify family members or call 120 as fast as possible and call an emergency vehicle. Because the emergency vehicle is equipped with highly trained ambulance personnel, after arriving at the scene, it can quickly make a preliminary diagnosis and notify the hospital with a chest pain center or treatment conditions to quickly start the emergency green channel to grab life-saving time. The most important thing for heart attack treatment is to seize the “golden time”. There are several treatment time points after the onset of heart attack, and 120 minutes is the most critical golden time to pass blood vessels. However, in reality, the awareness of patients, the level of doctors, the hospital treatment system and other factors have affected the time of revascularization, and the current situation of treatment is worrying. The construction of chest pain centers is currently being promoted precisely to shorten the rescue time by adopting rapid and standardized diagnostic protocols, significantly reducing the time to confirm the diagnosis of chest pain, reducing the time to STEMI reperfusion treatment, shortening the length of hospitalization, and the number of re-visits and re-hospitalizations, reducing the cost of unnecessary tests, and improving the quality of life and satisfaction of patients’ visits after surgery. However, many patients with chest pain, chest tightness and other symptoms, always like to carry, think that bear it will pass, and when they really can not carry, and then rushed to the hospital, often miss the best rescue time. He reminded patients that if they encounter chest pain aggravation, chest pain for more than 20 minutes without relief, they should immediately call the 120 emergency number. The most urgent task at present is to publicize more widely that “if you have chest pain, call for help early and call emergency 120”.
